12 health benefits of eating grapes

Grapes have been cultivated for thousands of years and are revered by several ancient civilizations for their use in winemaking.

There are many types of grapes including green, red, black, yellow, and pink. They grow in clusters and come in seeded and seedless varieties.

Grapes are grown in temperate climates around the world, including southern Europe, Africa, Australia, and North and South America. The majority of grapes grown in the United States come from California.

Grapes offer many health benefits due to their high nutrient and antioxidant content.

Here are the top 12 health benefits of eating grapes.

1. The grounds are packed with nutrients, especially vitamins C and K

Grapes are rich in several important nutrients.

One cup (151 grams) of red or green grapes contains the following nutrients:

  • Calories: 104
  • Carbohydrates:  27.3 grams
  • Protein:  1.1 grams
  • Fat:  0.2 grams
  • Fiber:  1.4 grams
  • Vitamin C:  27% of the daily reference intake (RDA)
  • Vitamin K:  28% of RDA
  • Thiamine:  7% of RDI
  • Riboflavine:  6% of RDI
  • Vitamin B6:  6% of RDA
  • Potassium:  8% of RDI
  • Copper:  10% of the RDI
  • Manganese:  5% of the RDA

One cup (151 grams) of grapes provides more than a quarter of the RDA for vitamin K, a fat-soluble vitamin vital for blood clotting and healthy bones.

They are also a good source of vitamin C, an essential nutrient and powerful antioxidant needed for healthy connective tissue.


Grapes contain many important vitamins and minerals, including more than a quarter of the RDA for vitamins C and K.

2. Grapes are high in antioxidants that can prevent chronic disease

Antioxidants are compounds found in plants, for example. They help repair damage to your cells caused by free radicals, which are harmful molecules that cause oxidative stress.

Oxidative stress has been linked to several chronic diseases, including diabetes, cancer, and heart disease.

Grapes are rich in a number of powerful antioxidant compounds. In fact, over 1,600 beneficial plant compounds have been identified in this fruit.

The highest concentration of antioxidants is found in the skin and seeds. For this reason, most research on grapes has been done using seed or skin extracts.

Red grapes contain a higher number of antioxidants due to the anthocyanins that give them their color.

The antioxidants in grapes remain present even after fermentation, which is why red wine is also high in these compounds.

One of the antioxidants in this fruit is resveratrol, which is classified as a polyphenol.

Many studies have been done on its benefits, showing that resveratrol protects against heart disease, lowers blood sugar, and protects against the development of cancer.

Grapes also contain vitamin C, beta-carotene, quercetin, lutein, lycopene, and ellagic acid, which are also powerful antioxidants.


Grapes are high in antioxidants and beneficial plant compounds that may protect against chronic health conditions, such as diabetes, cancer, and heart disease.

3. Plant Compounds May Protect Against Certain Types of Cancer

Grapes contain high levels of beneficial plant compounds, which may help protect against certain types of cancer.

Resveratrol, one of the compounds found in this fruit, has been well studied in terms of cancer prevention and treatment.

It has been shown to protect against cancer by reducing inflammation, acting as an antioxidant, and blocking the growth and spread of cancer cells in the body.

However, the unique combination of plant compounds found in grapes may be responsible for their anti-cancer benefits. In addition to resveratrol, grapes also contain quercetin, anthocyanins, and catechins — all of which may have cancer-fighting benefits.

Grape extracts have been shown to block the growth and spread of human colon cancer cells in test-tube studies.

What’s more, a study on 30 people over the age of 50 showed that eating 1 pound (450 grams) of grapes daily for two weeks decreased colon cancer risk markers.

Studies have also shown that grape extracts block the growth and spread of breast cancer cells, both in laboratory and mouse models.

Although studies on grapes and cancer in humans are limited, a diet high in antioxidant-rich foods, such as grapes, has been linked to a lower risk of cancer.


Grapes contain many beneficial plant compounds, such as resveratrol, which may protect against various types of cancer, including colon cancer and breast cancer.

4. Beneficial for Heart Health in Various Awesome Ways

There are several reasons why eating grapes is good for your heart.

It May help lower blood pressure

One cup (151 grams) of grapes contains 288 mg of potassium, which is 6% of the RDA.

This mineral is needed to maintain healthy blood pressure levels.

Low potassium intake has been linked to increased risks of high blood pressure, heart disease, and stroke.

A study in 12,267 adults showed that people who consumed higher levels of potassium compared to sodium were less likely to die of heart disease than those who consumed less.

May help lower cholesterol

Compounds found in grapes may help protect against high cholesterol levels by decreasing cholesterol absorption.

In a study of 69 people with high cholesterol, eating three cups (500 grams) of red grapes daily for eight weeks showed a decrease in total and “bad” LDL cholesterol. White grapes did not have the same effect.

What’s more, diets high in resveratrol, such as the Mediterranean diet, have also been shown to lower cholesterol levels.


Compounds in grapes and red wine may protect against heart disease. Grapes can help lower blood pressure and cholesterol.

5. May Lower Blood Sugar and Protect Against Diabetes

Grapes contain 23 grams of sugar per cup (151 grams), which may have you wondering if they’re a good choice for people with diabetes.

They have a low glycemic index (GI) of 53, a measure of how quickly a food raises blood sugar.

Additionally, compounds found in grapes can even lower blood sugar. In a 16-week study of 38 men, those who took 20 grams of grape extract daily saw their blood sugar levels drop compared to a control group.

Additionally, resveratrol has been shown to increase insulin sensitivity, which may improve your body’s ability to use glucose and, therefore, lower blood sugar.

Resveratrol also increases the number of glucose receptors on cell membranes, which may have a beneficial effect on blood sugar.

Managing your blood sugar levels over time is an important factor in reducing your risk of diabetes.


Although grapes are high in sugar, they have a low glycemic index. Additionally, compounds in grapes may protect against high blood sugar.

6. Contain Several Compounds Beneficial to Eye Health

The plant chemicals found in grapes may protect against common eye diseases.

In one study, mice fed a diet supplemented with grapes showed fewer signs of retinal damage and had better retinal function than mice that were not fed the fruit.

In a test-tube study, resveratrol was found to protect retinal cells in the human eye from ultraviolet A light. This may reduce the risk of developing age-related macular degeneration (AMD), a disease common eyepiece.

According to a review study, resveratrol may also help protect against glaucoma, cataracts, and diabetic eye disease.

Additionally, grapes contain the antioxidants lutein and zeaxanthin. Several studies have shown that these compounds help protect the eyes from blue light damage.

7. May Improve Memory, Attention, and Mood

Eating grapes can benefit your brain health and boost your memory.

In a 12-week study of 111 healthy elderly people, 250 mg of a grape supplement daily significantly improved scores on a cognitive test measuring attention, memory, and language against values reference.

Another study in healthy young adults showed that drinking about 8 ounces (230 ml) of grape juice improved both the speed of memory-related skills and mood 20 minutes after consumption.

Studies in rats have shown that resveratrol improved learning, memory, and mood when taken for 4 weeks.

Additionally, rat brains showed signs of increased growth and blood flow.

Resveratrol may also help protect against Alzheimer’s disease, although studies in humans are needed to confirm this.


Grapes contain compounds that may improve memory, attention, and mood and may protect against Alzheimer’s disease, although more human research is needed to confirm some of these benefits.

8. Contain Many Nutrients Important for Bone Health

Grapes contain many minerals necessary for bone health, including calcium, magnesium, potassium, phosphorus, manganese, and vitamin K.

Although studies in rats have shown that resveratrol improves bone density, these findings have not been confirmed in humans.

In one study, rats fed freeze-dried grape powder for 8 weeks had better bone absorption and calcium retention than rats that weren’t given the powder.

Human-based studies on the effect of grapes on bone health are currently lacking.
